Conditions at San Blas in August
August: Still Pumping, Slightly Less Pristine
August carries the green-season torch with an average swell of 4.5ft (1.4m) and a period of 13.2s. The consistency is remarkable: SSW supplies 78.2% of the waves, S another 16.4%, and the entire favorable window reaches 99.9%. Wave heights are still in prime range, with 56.8% of SSW at 3-5ft (1-1.5m), 18.9% at 5-6.5ft (1.5-2m), and a sprinkling of overhead energy.
Ideal wind is 55% - still good, but a step below July. The N/NNE/NE/ENE offshore quadrant covers 32.7%, while onshore S/SSW/SW/WSW flow is 22.7%. Rain increases to 6.95mm/day and water temps peak at 30.4°C, the warmest of the year. Expect clean, lined-up SSW sets in the morning, then a more textured, lumpier surface as the afternoon sea breeze develops. It remains a top-tier month, just with more emphasis on tide and time-of-day selection.
